ABSTRACT
Objective:To investigate the efficacy of Qingruxiao granules combined with tamoxifen in the treatment of breast hyperplasia and its effect on serum hypoxia-inducible factor-alpha (HIF-α), angiopoietin-2 (Ang-2) and prolactin (PRL) levels. Methods:Ninety-eight patients with breast hyperplasia admitted to Xi'an No.3 Hospital from June 2020 to January 2022 were retrospectively included in this study. They were divided into control and observation groups ( n = 49/group) according to different treatments. The control group was treated with tamoxifen alone. The observation group was treated with Qingruxiao granules combined with tamoxifen. Clinical efficacy, symptom score, ultrasound parameters (glandular layer thickness, longest diameter of mass, maximum diameter of hypoechoic area, inner diameter of lactating tube), endocrine hormone levels (estradiol, progesterone, and prolactin), HIF-α, and Ang-2 pre- and post-treatment, as well as the incidence of adverse reactions were compared between the two groups. Results:Total response rate in the observation group was significantly higher than that in the control group [93.88% (4/49) vs. 77.55%, χ2 = 5.33, P < 0.05). After treatment, breast mass score, breast pain, systemic accompanying symptom, and nipple discharge in the observation group were (1.34 ± 0.29) points, (1.02 ± 0.36) points, (0.68 ± 0.17) points, (0.97 ± 0.15) points, respectively, which were significantly lower than (1.57 ± 0.23) points, (1.45 ± 0.41) points, (0.95 ± 0.26) points, and (1.28 ± 0.26) points, respectively, in the control group ( t = 4.35, 5.52, 6.08, 7.23, all P < 0.001). The glandular layer thickness, the longest diameter of mass, the maximum diameter of hypoechoic area, and the inner diameter of lactating duct in the observation group were (9.45 ± 1.67) mm, (11.46 ± 3.68) mm, (14.37 ± 4.22) mm, and (1.23 ± 0.39) mm, respectively, which were significantly lower than (11.26 ± 2.51) mm, (16.33 ± 4.01) mm, (19.87 ± 5.01) mm, (1.54 ± 0.48) mm in the control group ( t = 4.20, 2.26, 5.88, 3.51, all P < 0.001). Serum estradiol and prolactin levels in the observation group were (122.35 ± 29.76) ng/L and (205.64 ± 36.42) IU/L, respectively, which were significantly lower than (139.76 ± 30.48) ng/L and (251.49 ± 41.87) IU/L in the control group ( t = 2.86, 5.78, both P < 0.05). Serum progesterone level in the observation group was (9.22 ± 1.57) μg/L, which was significantly higher than (7.18 ± 1.21) μg/L in the control group ( t = -7.20, P < 0.05). Serum HIF-α and Ang-2 levels in the observation group were (0.15 ± 0.05) ng/L and (0.98 ± 0.11) ng/L, respectively, which were significantly lower than (0.24 ± 0.07) ng/L and (1.49 ± 0.22) ng/L in the control group ( t = 7.32, 14.51, both P < 0.001). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Qingruxiao granules combined with tamoxifen can effectively improve clinical symptoms, reduce tumor size, regulate endocrine hormone levels, decrease the expression of angiogenic factors in patients with breast hyperplasia, and is highly safe.
ABSTRACT
Natural collagen peptides are collagen hydrolysates. Because of their unique physicochemical properties and excellent biological activities, collagen peptides have been a research hotspot of cosmetic raw materials development and skincare efficacy improvement. Combined with the needs of the skincare efficacy and the development trends of cosmetics, the extraction methods and their structural characteristics of natural collagen peptides were summarized in detail. The applications and its research progress in skincare efficacy of collagen peptides, such as moisturizing and anti-wrinkle, trophism and anti-aging, filling and skin regeneration were expressed with emphasis. Finally, the development and practical applications in cosmetics of natural collagen peptides were adequately prospected.

Objective To evaluate the clinical benefits and safety of endoscopic thyroidectomy via bilat -eral-nipple approach and breast approach by comparison with conventional open thyroidectomy .Methods 59 pa-tients undergoing open thyroidectomy , 76 patients undergoing endoscopic thyroidectomy via breast approach , and 122 patients undergoing endoscopic thyroidectomy via bilateral-nipple approach were retrospectively analyzed . Patients'age, operation duration, intraoperative blood loss, the first day drainage volume after operation , postop-erative hospital stay , the incidence of complications , pain visual analogue score ( VAS) , postoperative satisfaction rate as well as the evaluation of cosmetic results were compared among different groups .Results No significant difference was observed in the intraoperative blood loss and the postoperative hospital stay among different groups . The operation duration and the first day drainage volume after operation in the endoscopic thyroidectomy groups ((103.5 ±26.2)min vs (108.1 ±23.9)min,(106.5 ±31.0)ml vs (117.4 ±38.8)ml)were significantly high-er than those in the open thyroidectomy group((65.3 ±22.4)min and (50.5 ±23.8)ml)(P<0.05, respective-ly).No significant difference was observed in the complication incidence among different groups .On the first day after operation, VAS of the endoscopic thyroidectomy groups (2.8 ±0.4 vs 2.9 ±0.4)was significantly lower than that of the open thyroidectomy group(3.8 ±0.6)(P<0.05, respectively), even though on the second and the third day no significant difference was observed among different groups .Besides, postoperative satisfaction rate and the evaluation of cosmetic results in endoscopic thyroidectomy groups were significantly higher than those in the open group(P<0.05, respectively).Furthermore, 90 days after operation, the satisfaction rate and the eval-uation of cosmetic results in the endoscopic thyroidectomy group through bilateral -nipple approach (96.7%,8.8 ± 0.9)were significantly higher than those in the endoscopic thyroidectomy group through breast approach (92.1%, 7.3 ±0.7)(P<0.05, respectively).Conclusions Endoscopic thyroidectomy is a feasible and safe procedure . Endoscopic thyroidectomy through bilateral-nipple approach has a higher long-term satisfaction rate as well as bet-ter cosmetic results , which is an ideal choice of thyroidectomy .
